Answer 1

Ответ:

43/24

Пошаговое объяснение:

-3*1/8+2*5/6-(-2*7/12)-(-1*2/3)

-3/8+5/3-(-(7/6))-2/3

-3/8+5/3+7/6-2/3

43/24

Answer 2

Let's simplify the expression step by step:

-3 * 1/8 = -3/8 2 * 5/6 = 10/6 (which can be simplified to 5/3) -2 * 7/12 = -14/12 (which can be simplified to -7/6) -1 * 2/3 = -2/3

Now, let's substitute these values back into the original expression and simplify further:

-3/8 + 5/3 - (-7/6) - (-2/3)

Now, let's deal with the subtraction of negative numbers by changing the signs:

-3/8 + 5/3 + 7/6 + 2/3

To add these fractions together, you need to find a common denominator, which in this case is 24:

(-9/24) + (40/24) + (28/24) + (16/24)

Now that all the fractions have the same denominator, you can add them:

(-9 + 40 + 28 + 16) / 24

Adding the numerators:

(75/24)

Now, you can simplify this fraction:

75/24 = 25/8

So, the final result is 25/8.
